Fumie finds the astronomy club members sleeping in the same room after they collapsed from exhaustion the previous night, and she forbids them from taking part in club activities for one night. The next day, three guys hit on Hime and two literature club members, and Fumie tries to interfere at first, but when Saku goes to help, he trips and falls into the guy's fist. Mihoshi and Hime manage to take care of the three guys, and Saku is taken inside and cared for, though he only has a small cut. While the other astronomy club members are taking a bath, Fumie talks with Saku about the astronomy club's activities and they decide to invite the literature club members the next night to show them what the astronomy club does at night. Hime takes care of pointing out several constellations and the Milky Way, and everyone enjoys the night of stargazing.

The astronomy club members wake up late the next morning and first spend some time warming up in the outdoor baths. Ayumi Omi notices Roma stressing over studying for university entrance exams, and takes him to buy a study book and then have dinner at a fancy restaurant. The astronomy club members wait until the moon sets on the third night and spend their final night in the mountains stargazing and taking photos. The members use some eyepieces Mihoshi brought to find Saturn, which is an entrancing sight for everyone. The following spring, Mihoshi has succeeded as club president after Roma graduated and entered into university with Ayumi. Everyone puts in more effort this year for recruiting members, since they are now one member short, and are again in danger of getting disbanded.
